actually, even for a healthy eating cham, its probably good to occassionally go 2-4 days without any food, gives their digestion a chance to catch up and get rid of stuff that is harder to digest, (like exoskeletal debris, excess calcium etc) helps pevent impaction, calcium buildup,etc. it would take weeks for a healthy cham to starve to death, but on the other hand, not eating is not neccessarily the same as going without food. (going without food implies not being fed , not eating, implies possible problems. short term hunger strikes arent all that uncommon, but if there are periods of not eating, something else may be wrong and other indicatorrs should be looked at extra closely. jmo
